DEFINITION: Anguis fragilis , Pseudopus apodus , and all descendants of their last common ancestor.

DIAGNOSIS: This clade is diagnosed by 47(1) jugal curved (rather than angulated), 67(0) frontal not contacting the palatines, 240(1) lateral processes of the atlas reduced, and 269(0) absence of an anterior process of the interclavicle.

COMMENTS: Anguins include Anniella and Pseudopus apodus ; one of the more often sampled and illustrated species of ‘‘ Ophi- saurus ’’. Anniella is sometimes separated into its own ‘‘family’’ Anniellidae (for a history of the phylogenetic and taxonomic placements of Anniella , see Gao and Norell, 1998). Importantly, the current analysis does not find a close relationship between Anniella and Apodosauriscus minutus , in contrast to the findings of Gauthier (1982). However, additional, undescribed, remains of Apodosauriscus (mentioned in Gauthier, 1982) will add critical data to the analysis and may bolster Gauthier’s (1982) hypothesis upon their description. Even so, the current phylogenetic hypothesis reflects available data, suggesting that Anniella is an anguin close to Anguis .
